   DESIGN SYSTEM - BUTTON STANDARDS

/*
   BUTTON ORDER STANDARD (GLOBAL)
   ==============================
   
   For global web standards and SaaS applications:
   
   • Secondary Button: LEFT
   • Primary Button: RIGHT
   
   This follows the most familiar pattern for users worldwide:
   - Cancel/Back actions on the left
   - Continue/Confirm actions on the right
   - Consistent with most SaaS platforms and web applications
   
   Examples:
   [Cancel] [Continue]
   [Back] [Next]
   [Watch Demo] [Explore Solutions]
   [Keep USD] [Switch to EGP]
   
   IMPORTANT: Always follow this order for consistency across the entire application.
